A classic fairytale gets a dark and scary makeover with the release of Snow White and the Huntsman this week. Twilight's Kristen Stewart leads the cast as the titular princess, who's exiled to a castle tower by her evil stepmother Queen Ravenna (Charlize Theron).

"I think it's a return to the source of the original material," Frost said. "The dwarves are there as a little bit of light comic relief, but apart from that I think it's going to be a very dark, eerie, bleak, frightening, creepy, exciting fairytale."

Winstone praised his co-star Stewart, saying that he was impressed by how quickly she adapted to working with the eight dwarves.

"It's not easy for her, you've got eight actors having a laugh playing guys that are dwarves. We all know one another, and to come into that circle of men and perform the way she did was fantastic. She's a great little actress," he said.
